Purchased as a souvenir from an overseas trip. I displayed it as interior decoration for a while, and after my child was born, we used it for their first puzzle play. The experience of grasping the pieces is great for finger dexterity! Each part is marked on the back of the base. (Photos 2, 3) When shipping, I will cover the markings. If you are concerned, you can cover them with a sticker, etc. There is what appears to be ink staining on the back. (Photo 3) *Please be sure to read the profile before purchasing.
